3. Broadcasting (Basal application)
 To spreading fertilizers uniformly
 Dense stand roots
 large doses
 Rock phosphate

4. Top dressing
 Particularly nitrogenous fertilizers
 Closely sown crops

5. Disadvantages of Broadcasting
Nutrients cannot be fully utilized
Weed growth is stimulated
Nutrients are fixed in the soil

6. Placement
Placement of fertilizers in soil
The most common methods of placement are
as follows:
i. Plough sole placement
ii. Deep placement
iii. Localized placement

7. Drilling
 Same row but at different depths

10. Pellet application
 2.5 to 5 cm
 1:10 Ratio
 Paddy crops

11. Methods Of Applying Liquid
Fertilizers
Starter solutions
 N, P2O5 and K2O
 1:2:1 and 1:1:2
The disadvantages of starter solutions are
 Extra labour is required
 The fixation of phosphate is higher

12. Foliar application
 One or more nutrients
Advantages
 Nutrients absorbed by leaves
 For minor nutrients
like iron, copper, boron, zinc

13. Fertigation

14. Injection into the soil
Two types of Injection
Non pressure Type
 On surface or in furrows
Pressure Type
 In furrows
 12-15 cm

15. Aerial application
